An extinction of one species could destroy an ecosystem if an animal depended on the extinct animal for food. Then that animal would die off, which could affect even more animals.

Invasive species cause harm to the environment, because their like unknown organisms that exist, and replace original species. I might be able to change the environment/ecosystem.
if it leaves an environmental niche, then another, already existing, species might take that niche; or a new one might evolve to fill it.
The two main ways in which a foreign species may lead to the extinction of an indigenous species would be through predation and competition for resources.Predation would involve the direct consumption of the species by the invading foreign species such as a bug that decimates a plant population that it finds appetizing when there was no prior insect that would eat this plant.Competition for resources would be due to the invading species having a competitive advantage over the indigenous species for acquiring the resource. An example of this again might include an invading bug which matures to adult form earlier in the season than an indigenous bug and is able to eat all of a plant species that the home-town bug requires for survival before they can emerge, feast and reproduce.There are a multitude of these types of situations that can involve primary interactions between the two species (invading and indigenous that goes extinct) or secondary/tertiary interactions through a chain of species in the food web of the local ecosystem.
Changes in an ecosystem can lead to disruptions in the balance of species and their interactions, potentially causing declines or extinctions of certain organisms. This can result in altered food webs, where some species may thrive while others struggle, leading to a loss of biodiversity. Additionally, changes such as climate shifts or pollution can affect habitat quality, further stressing the ecosystem and its resilience. Overall, these changes can create a cascade of effects, impacting ecosystem services that humans rely on, such as clean water, pollination, and carbon sequestration.
Yes, if you are going to save a species then they might as well be saved from extinction.
EXTINCTION
lo
Well, environmental factors like climate change can cause a species to die out because they were not able to adapt to their environment.
mass extinction: When at least 50 % of the species on Earth go extinct within a relatively short amount of time.
an invasive specie is an animal that is dangerous to an ecosystem. so a snail might be an invasive specie to one ecosystem, but to another, they may be part of the ecosystem. No that is completely wrong a invasive species is a species that came to one place from another place and it doesn't belong Dont listen to that idiot it isn't an invasive species it's from North America and so no it is not. Now theres a real answer.

If an ecosystem lost all its plant species, it would disrupt the food chain as plants are primary producers. This would lead to a cascade effect, impacting herbivores, predators, and ultimately the entire ecosystem. Nutrient cycles would also be disrupted, affecting soil health and ecosystem stability.
if it leaves an environmental niche, then another, already existing, species might take that niche; or a new one might evolve to fill it.
Partially,because in an ecosystem,animals of similar species. While in another, animals of far different species might be present.
When exotic species are introduced into a new ecosystem, they often don't encounter the same factors that controlled the exotic species population or growth that was in the original ecosystem.
Yea im pretty sure but i might be wrong
